Suddenly we have some reports which show this error message.
Looking at the dev console we see the following JS error:
TypeError: Cannot read properties of undefined (reading 'source') at SVGGElement.<anonymous> (timelines.js:155:26) at SVGGElement.<anonymous> (d3.js:792:21) at d3.js:962:16 at Ae (d3.js:968:30) at K.each (d3.js:961:12) at K.html (d3.js:791:36) at timelines.js:153:6 at NL (timelines.js:240:3) at LineAreaBarPostRender.js:402:3 at VV (LineAreaBarPostRender.js:453:3)
Debugging we have seen it's failing because following line:
return Icons[icon].source; contains "balloon" as icon, and apparently this icon don't exist anymore. We are running version v1.47.6. It seems something ahs changed recently, maybe this.
How can we fix it?
